Lee Valley sell an aluminum face plate, normally aluminum faceplates
are considered light weight, but if your thinking wooden, aluminum
should do the trick

in the winter 2007 Woodturning Design there is an article on turning Xmax
ornaments. This guy made what was essentially a face plate by tapping a
thread in a wood circle.

Now I can think of a myriad of useful reasons to make wooden face plates.
However my Powermatic 3520B has a 1.25 x 8tpi head stock. Granger wanted
about $160 for that tap, which seems absurd.

Anyone used MDF to make face plates? Where can I get a 1.25" x 8 tpi tap
for less than the national debt?
